I think getting a remote fitting (custom made) is nice. I used to make and sell them, but no longer. Unlike some pistols, you can put in a male QD where the brass screw goes and you do not need to plug the marker with a 12 gram powerlet to stop leaks out the front, you can simply leave it there and use it as you wish or choose not to. It still holsters well, and allows you to run remote, which is much cheaper.
I did not like the bottomline kit. I have the hopper adaptor, and it only fits the small size feednecks.
I highly recommend the Ronin Gear holster, it fits the pistol well, is well designed, and is very inexpensive for the quality it is made with. I also replaced the grip panels with Dye Basic Stickies (which required some minor modification of the gripframe).
Strengths:
Semi-auto, Fast recharge, Holsterable, Best consistancy of pistols, cheap
Weaknesses:
Long trigger, somewhat cheap construction, non-standard
Review:
I've had a lot of fun with mine! I had two, and sold one once I realized how stupid using two at a time was. I researched very carefully before choosing the PT Punisher and I'm glad I did. Only the Palmer Squall is better (at $300 US!). The PT Enforcer is an older version of this one, and the clips and cocking are inferior. The Zeus and Zx are newer versions, but are functionally the same. The Punisher and the both the Core and Paintball Online Professional are identical in everything but a couple cosmetic details. The PT Extreme looks cooler and is often considered superior, but is truly not. The Extreme has velocity problems and they worsen as the gun is used more.
The PTP is surprisingly accurate, though not as accurate as a marker with a good barrel. The barrel is very large (I guess so you don't break paint). The ball detente is not so good, and if you run with the pistol you can lose shots out the barrel as it swings in your hand. The rate of fire is upwards of 8 BPS and I'm not that fast on a trigger. The gripframe is only plastic, so its not very durable, but you won't be using it that often anyways.
Sadly, the threads are mostly non-standard, and the marker is designed so that you need to use their parts. The people at paintball online do not know anything about the marker so they're no help. The cocking mechanism is identical to the Core Sharc, and I think you could use those parts. The little brass screw under the CO2 slot is not the standard 1/4 NPT fitting, instead it is an African garden hose fitting!
I highly recommend the Ronin Gear holster, it fits the pistol well, is well designed, and is very inexpensive for the quality it is made with. I also replaced the grip panels with Dye Basic Stickies (which required some minor modification of the gripframe).
All in all, it's cheap, looks good, and there's no reason not to have one! I have so much fun running around with just the pistol sometimes, and the number of people I've scared the bejeezus out of is climbing. Just remember to oil it a LOT!
Chrono figures: 305, 304, 302, 298, 290, 295, 293, 289, 289, 280 Out of the box on a snowy day with a 12g powerlet fired once every 5 seconds.
Conclusion:
As the best pistol in its price range, I give it a 9 / 10. You can get them for $70 with a holster from Ronin!
